Filter by:Fibrinogen is a unique precursor of fibrin and cannot be compensated for by other coagulation factors. If plasma fibrinogen concentrations are insufficient, hemostatic clots cannot be formed with the appropriate firmness. In severe traumatic brain injury(TBI) patients, plasma fibrinogen concentrations decrease earlier and more frequently than other coagulation factors,predicting massive bleeding and death. The purpose of this study is to try early injection of fibrinogen concentrate in severe isolated traumatic brain injury and investigation the effect of it on post bleeding and complications.
The purpose of this study is to evaluate early and delayed effects of Transcranial LED Therapy (TCLT) and determinate whether this therapy is effective for cognitive rehabilitation of Diffuse Axonal Injury patients after Traumatic Brain Injury.
Traumatic brain injuries (TBI) are one of the most common reasons for patients to attend the emergency department (ED). 90% of patients with TBI are defined as mild TBI (mTBI). A small minority of patients with mTBI would show pathological computed tomography (CT) results and even fewer need neurosurgical intervention. Nevertheless, complications would be so severe, if neurosurgical intervention is delayed, that it has become common practice to subject all patients with mTBI to CT. The high number of CT scans has an impact on health care resources but may also involve risk by subjecting patients through potentially harmful ionizing radiation. Several independent research groups have attempted to optimize CT use in mTBI patients by forming guidelines that aim to identify patients at high risk for intracranial complications. Most guidelines have been published in the past 15 years and have been validated both prospectively internally and externally; all guidelines have been shown to be safe when implemented in clinical use with few missed complications. However the number of CT scans has not been reduced dramatically, in some cases it has even increased. In 2013, the new Scandinavian guidelines (SNC13) were published. They are the first guidelines that use a biomarker, S100B, as a tool for managing patients with mTBI. Although S100B has a low specificity for intracranial complications, a high sensitivity makes it suitable to be implemented into clinical practice as a tool for CT reduction. Previous SNC guidelines have been compared to other prominent guidelines with impressive results. The SNC13 have been externally validated in a retrospective study from the USA that was underpowered for important outcomes. Nevertheless, SNC13 have already been partially implemented in clinical practice in Scandinavia. However, a strict multicenter validation has not been performed yet nor a systematic comparison to other available guidelines. Our primary aim is to validate the performance of the SNC13 in predicting intracranial complications in adult patients presenting with traumatic head injury in Swedish hospitals. A secondary aim is to compare the performance of SNC 13 with 6 other clinical guidelines, with respect to important outcomes. Moreover, to explore the performances of different biomarkers in predicting intracranial complications in predefined subgroups of TBI. Finally, to evaluate the possibility of further improvement of the SNC13.
This study aims to develop and evaluate biomarkers using non-invasive optical coherence tomography (OCT) and OCT angiography (OCTA) as well as ultra-widefield (UWF) fundus photography to assess the structure and function of the retinal and choroidal microvasculature and structure in persons with mild cognitive impairment (MCI) and Alzheimer's Disease (AD), Parkinson's Disease (PD), or other neurodegenerative disease, diseases as outlined.
In this study, our objective is to determine the effect of two different nerve stimulation types in changing sleep architecture.
In Denmark, about 120,000 people suffer from brain damage, of whom approx. 75,000 with brain damage after stroke. Serious and often lasting vision impairments affect 20% to 35% of people after stroke. Vision is the most important sense in humans, and even smaller permanent injuries can drastically reduce quality of life. Vision impairments after brain damage inhibits rehabilitation and enhances other invalidating effects. Reduced vision results in impaired balance, increased risk of serious falls, increased support needs, reduced quality of life, and impaired ability to perform activities of daily living. Restoration of visual field impairments occur only to a small extent during the first month after brain damage, and therefore the time window for spontaneous improvements is very limited. Hence, brain-impaired persons with visual impairment will most likely experience chronically impaired vision already 4 weeks after brain injury and the need for visual compensatory rehabilitation is substantial. Neuro Vision Technology (NVT) is an supervised training course where people with visual impairments are trained in compensatory techniques using special equipment. Through the NVT process, the individual's vision problems are carefully investigated and personal data is used to organize individual training sessions that practice the individual in coping with situations that cause problems in everyday life. The purpose of this study is to investigate whether rehabilitation with NVT can cause significant and lasting improvement in functional capacity in persons with chronic visual impairments after brain injury. Improving eyesight is expected to increase both physical and mental functioning, thus improving the quality of life. Participants included in the project will be investigated in terms of both visual and mental functions, including quality of life, cognition and depression. Such an investigation has not been performed previously and can have a significant impact on vision rehabilitation both nationally and internationally.
The purpose of this study is to assess the safety and efficacy of daily morning exposure to colored light in patients receiving acute inpatient rehabilitation services for stroke, traumatic brain injury, or non-traumatic brain injury with sleep disturbances such as poor nighttime sleep and/or excessive daytime sleepiness.In a two-arm randomized placebo-controlled study with pre-exposure and post-exposure assessments, we are comparing the effects of daily morning exposure to either blue light or red light on objective sleep quality, subjective sleep quality, functional rehabilitation outcomes, cognitive symptoms, fatigue, and neurological symptoms.
The most common motor deficiency after stroke or traumatic brain injury is hemiparesis. Most hemiparetic patients recover walking, but rarely with a speed permitting easy ambulation outdoors with family or friends. One of the mechanisms of gait impairment in hemiparesis is insufficient active hip flexion during swing phase, which leads to insufficient ground clearing at swing phase, with associated gait slowness and risks of fall. The main hypothesis behind the present study is that insufficient hip flexion during hemiparetic gait is partly due to overactivity of rectus femoris. Focal treatment of lower limb muscle overactivity using botulinum toxin has not been demonstrated to increase walking speed in hemiparesis as yet. However, most studies have focused distally, on improving foot dorsiflexion only. The purpose of this study is to compare the effects of botulinum toxin injection and placebo in rectus femoris (RF) + plantar flexors versus plantar flexors only.
The primary objective of this study is to prospectively assess in randomized fashion whether short term anti-seizure prophylaxis in traumatic brain injured patients decreases the incidence of seizures in the early post-injury period. A secondary objective is to evaluate whether there are differences in mortality, hospital length of stay, functional outcome at hospital discharge, hospital cost, discharge status (home, rehabilitation facility, etc.) for patients who receive and do not receive anti-seizure prophylaxis.
Head injury is a common and devastating condition that can affect people at any stage of their lives. The treatment of severe head injury takes place in intensive care where interventions are designed to protect the brain from further injury and provide the best environment for recovery. A number of different monitors are used after head injury, including a monitor called microdialysis, to measure how the brain is generating energy. Abnormalities in these monitors guide doctors to the right treatments when the brain is at risk of further injury. There are lots of ways that the brain can be injured further after head injury such as raised pressure in the skull from brain swelling, low oxygen levels and low glucose levels. In this study we aim to combine information from all of these monitors to figure out what the underlying problem is and choose the right intervention to treat the problem that is affecting the patient at the time and compare this with previous treatment protocols to see if it improved outcome. Aim: To establish and validate a protocol to treat abnormalities in a microdialysis measure called lactate/pyruvate ratio (LPR) that reflects how cells are generating energy, and compare it with patient cohorts not being monitored using the current protocol.
